05-18: Ashok’s paper on 13C hyperpolarization in powdered diamond goes live in Science Advances! Congratulations to Ashok and all co-authors.

The ability to optically polarize the spin of NV centers in diamond under ambient conditions has long been considered a valuable resource for nuclear spin hyperpolarization and MRI. Unfortunately, the misalignment between the external magnetic field and the NV axis inherent to a powder – the preferred geometry in the above applications – has proven an obstacle difficult to surmount. The work by Ajoy et al. demonstrates efficient 13C polarization in a diamond powder under ambient conditions and in the presence of mild optical and MW excitation, thus paving the route to portable, affordable hyperpolarization platforms of widespread applicability.
